Corrosion Inhibitors

Corrosion inhibitors are essential components in the formulation of water-miscible metalworking fluids. The primary function is to minimise the corrosive effects of water-based fluids on ferrous and non-ferrous metals. Besides the corrosion inhibitor components as a function of their chemical composition, they can also provide emulsification, lower foaming tendency and enhanced lubricity making them useful multifunctional additives. Metalworking fluid applications include soluble oils, semi-synthetic and fully synthetic fluids as well as cleaners.

Corrosion inhibitors components provided by Lankem may be used to boost corrosion inhibition properties of water-based fluids for steel, iron, aluminium, other metals, and neat oil lubricants for ferrous based metals.

These products are based on phosphate esters, imidazolines and fatty acid esters:

Lanphos PE74, Lanphos PE35 and Lanphos PE36 phosphate esters provide corrosion protection for ferrous metals and aluminium for soluble oil and semi-synthetic metalworking fluids. Lanphos TEP4 provides corrosion inhibition in the formulation of synthetic metalworking fluids.

Lansurf CO12 and Lansurf CO40 are effective nonionic secondary emulsifiers using the formulation of soluble oils and semi-synthetic metalworking fluids. They are particularly suited to the emulsification of vegetable oils in addition to mineral oils and ester-based lubricants.

Lansurf CDE and Lansurf CDE-G are effective nonionic secondary emulsifiers using the formulation of soluble oils and semi-synthetic metalworking fluids. They are particularly suited to the emulsification of mineral oils and ester-based lubricants. In addition to emulsification, they provide beneficial corrosion inhibition characteristics.
